Need help with miscellaneous moving tasks and lifting in UK

I’m moving flats next month and need a flexible helper for miscellaneous moving tasks. The job isn’t heavy furniture transport, but I’ll need assistance with lifting small boxes, rearranging items in my new place, carrying items up to a couple of flights of stairs, and maybe some basic furniture assembly or disassembly. Materials will be provided, and I’d appreciate someone who is careful with fragile items and respects building access rules. I’d like to schedule a 3–4 hour session and can confirm exact times once we agree on availability. Comfort with navigating stairs, a helper who arrives with a positive attitude, and basic moving equipment would be ideal.
